And, if you use the pf, pf2, and pf3 parameters of edismax, with boosting,
you can assure that the closest matches always appear first.
And assuming you do index-time synonym expansion.

No, there isn't a tokenizer that'll do what you want that I know
about. Really, I suspect you need to back up a bit and re-think the
problem. It looks to me like you've taken a path that's going to cause
you endless grief when, as Jack says, phrase searches are built in to
the tokenization process.
Best,
Erick

Query by phrase is a core feature of tokenized text in Lucene and Solr, so
there is no need to use a pattern token filter for that purpose. And yes,
doing so pretty much breaks most token filters that would assume that the
text is tokenized.

Hi Eric.
No, that doesnt fix the problem either (I have tested this previously and
did so again just now)
Since the PatternTokenizerFactory is not tokenizing on whitespace(by
design
since I want the user to search by phrase), the phrase "marina former fort
ord" (for example) does not get turned into four tokens ("marina",
"former",
"fort" and "ord"), and so the SynonymFilterFactory does not create
synonyms
for them (by design)
the original question remains: is there a tokenizer/plugin that will allow
me to synonym words in a unbroken phrase?
note: the reason I dont want to tokenize the data by whitespace is that it
would cause way to many results to get returned if I, for example, search
on
"new" or "st" ... However, I still want to be able to include "fort saint
john" in the results if the user searches for "ft st john" or "fort st
john"
or ...
